我正在使用 Facebook Graph API v2.0。以下调用

[FBRequestConnection startWithGraphPath:@"/me/picture" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
    if (!error) {
        NSLog(@"%@", result);
    } else {
        NSLog(@"%@", [error userInfo]);
    }
}];

导致此错误：

{
    NSLocalizedDescription = "Response is a non-text MIME type; endpoints that return images and other binary data should be fetched using NSURLRequest and NSURLConnection";
    "com.facebook.sdk:ErrorSessionKey" = "<FBSession: 0x10f036250, state: FBSessionStateOpen, loginHandler: 0x100073a40, appID: 863523550341327, urlSchemeSuffix: , tokenCachingStrategy:<FBSessionTokenCachingStrategy: 0x10f0339c0>, expirationDate: 4001-01-01 00:00:00 +0000, refreshDate: 2014-07-27 17:20:14 +0000, attemptedRefreshDate: 0001-12-30 00:00:00 +0000, permissions:(\n    installed,\n    \"public_profile\",\n    email,\n    \"user_birthday\",\n    \"user_location\",\n    \"user_friends\"\n)>";
    "com.facebook.sdk:HTTPStatusCode" = 0;
}

有谁知道为什么会这样？我真正需要的只是一个包含我个人资料图片网址的回复。在 2012 年及更早的时候，也有人问过类似的问题，但此后 API 发生了变化。请不要将此标记为重复，除非您确实确定将我重定向到的问题有一个有效的解决方案。我尝试了其他几种替代方法，例如自己启动连接并使用诸如“/me?fields=picture”之类的图形路径，但它们都会导致相同的错误。

看来我原来的电话需要一张图片。要获得基于文本的响应，该响应为个人资料照片提供 url，以下对我有用：

 [FBRequestConnection startWithGraphPath:@"me?fields=picture.height(500),picture.width(500)"completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
            if (error) {

            }
}];

对于我使用的新 Facebook Graph API：

FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                              initWithGraphPath:@"/me?fields=id,name,picture" //As many fields as you need
                              parameters:nil
                              HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
                                      id result,
                                      NSError *error) {
    if (!error){
        NSDictionary *picture = [(NSDictionary*)result objectForKey:@"picture"];
        NSDictionary *data = [picture objectForKey:@"data"];
        NSString *url = [data objectForKey:@"url"];
        NSData *dataImage = [NSData dataWithContentsOfURL:[NSURL URLWithString:url]];

    }
}];

借助此 URL 模板加载个人资料图片

    NSString *imgUrl = [NSString stringWithFormat:@"http://graph.facebook.com/%@/picture", user.id];
